The figure shows the German supersites that belong the HD(CP)² project. Blue lines denote the boundaries of the simulation domain. The solid line describes the area of the forcing data and the dashed line the actual HD(CP)² simulation domain.

The aim is maintaining a continuous data stream starting in 2007 (if possible) and extending it with most recent data at all supersites. The data provided will be microwave radiometer, cloud radar and lidar and auxiliary data, i.e. soundings or radiances.
